IS E-PEAS’ RF (RADIO FREQUENCY) ENERGY HARVESTING FOR YOU?
Let’s assume that you work with battery powered IoT wireless devices that operate within wireless waves rich environments. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.
But there might be enough of energy provided by the wireless emitters surrounding your devices that you could use to power them.
Those emitters include:
- GSM900 (BTx) 925-960 MHz
- GSM1800 (BTx) 1805-1880 MHz
- 3G (BTx) 2110-2170 MHz
- WiFi 2400-2500 MHz
And if not, you can equip the environment with dedicated emitters emitting power at 868MHz (Europe) or 915MHz (USA).
Depending on the power emitted by the source and the distance from the source (from 10’s of cm up to 15m), typical power levels you can harvest range from 10µW to mWs.
When properly selected and sized (frequency compatibility with available sources), an antenna and a balun (provided by e-peas for all above mentioned frequency ranges) combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient RF power.
Using e-peas’ RF energy harvesting, you will avoid typical operating costs associated with battery replacement.
WHAT EXACTLY DO WE OFFER?
Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries from received RF power levels as low as -19.5dBm.
e-peas offers you 2 AEM [Ambient Energy Manager] references:
- The AEM30940 allows you for harvesting energy from -18.5dBm up to 10dBm using properly selected external antenna, balun and rectifier
- The AEM40940 integrates an RF rectifier and allows you for harvesting energy from -19.5dBM up to 10dBm using a properly selected external antenna and balun.
HOW DO WE DIFFER FROM COMPETITION?
Both references are based on e-peas unique AEM platform offering:
- top energy conversion efficiency
- the fastest supercapacitor charge
- the lowest cold-start power
- the smallest footprint and associated components BOM
In addition, you will get direct access to engineering support by our designers.
